The girls disappeared while riding bikes in Evansdale last July. They were found dead in December in a rural county park. No arrests have been made in the case.

Two girls were abducted in Dayton last month. Authorities believe Michael Klunder took the girls. One was able to escape, but Kathlynn Shepard is still missing.

Investigators looking into the Collins, Cook-Morrissey case have said they are looking at Klunder as a possible suspect in their case.

Chief Deputy Rick Abben of the Black Hawk County Sheriff's Department released the statement:

"Investigators with local, state and federal law enforcement agencies continue to follow-up on information obtained in the disappearance and death of Lyric Cook-Morrissey and Elizabeth Collins.

"With regards to any connection between Michael Klunder and the Evansdale case, investigators are still tracking his actions and whereabouts around the date of the disappearance and are still sifting through information to try and determine whether there is or is not any connection.

"While Mr. Klunder's actions in Dayton are of interest to this case, our focus remains on all aspects of the investigation and he is not the sole focus of our attention. Other leads continue to be uncovered and investigators continue to follow-up on any and all information that comes in.

"We will continue to keep the public up to date as information becomes available."
